How to open a CrossFit gym, step by step

Opening a CrossFit gym takes ten steps, and the order matters. Numbers and audience come first, then the space and the permits, and only then the equipment and the presale. A CrossFit gym, often called a box, is a group training space with barbells, rowers and rings. Every class has a coach and a capacity. This guide walks through the ten steps and what to decide at each one. It ends with a twelve-week calendar and the costliest mistakes.

The ten steps at a glance

  1. 1.Decide what you are selling, and to whom.
  2. 2.Run the numbers: what it costs to open and what it costs to stay open.
  3. 3.Decide whether to affiliate with the CrossFit brand.
  4. 4.Choose the space and negotiate the lease.
  5. 5.Get the permits, insurance and paperwork your area requires.
  6. 6.Hire qualified coaches, and a head coach if you are not one.
  7. 7.Buy the equipment your biggest class needs.
  8. 8.Build the timetable and the membership plans.
  9. 9.Sell before the doors open.
  10. 10.Plan the first week as if it were the most important one.

Steps 4 to 6 run in parallel. The permit depends on the space, and the space depends on what the permit allows. Everything else follows the list.

1. What you sell, and to whom

Before you look at a single unit, write one sentence about the person who will train with you. Someone who works nine to six and can only come at 7:00 or 19:00? An experienced athlete looking for a box near home? Someone who has never touched a barbell?

That answer shapes everything else: the timetable, the class size, the price, even the floor. A gym for beginners needs an on-ramp course and more coach time per person. A gym for experienced athletes needs more barbells and more room to lift.

  • The core audience: who they are, where they live, when they can train.
  • The core product: group classes, open gym, small groups or personal training.
  • What sets you apart from the gyms within fifteen minutes of your door.
  • How many members you need to cover your costs, which comes from the next step.

2. The numbers, before the space

There are two separate sums. The first is the investment: what you spend before you open. The second is the monthly cost: what leaves your account every month, however many people turn up.

The figure that decides whether the gym survives is the break-even point. Divide the monthly cost by what an average member pays, after sales tax and payment fees. The result is the number of members at which you stop losing money.

The break-even sum

Fixed monthly cost (rent, wages, insurance, accounting, software, energy): ______

Average revenue per member, excluding sales tax and payment fees: ______

Break-even = fixed monthly cost ÷ average revenue per member = ______ members

Members the presale needs to secure before opening: ______

Each cost category, how to estimate it and what tends to be forgotten has its own guide. How much does it cost to open a gym?

3. Affiliation, if you want the CrossFit name

CrossFit is a registered trademark. To call your gym CrossFit, and use the name in classes and advertising, you have to be an affiliate. Affiliation is not a franchise. The gym stays yours, and you set the timetable, prices and programming.

According to the official page, checked in October 2026, the annual fee ranges from US$2,500 to US$4,500. It depends on location. There is also a one-time application fee of US$1,000. One team member must hold the Level 1 certificate before the gym opens. The process usually takes two to four weeks, and can be stretched to a year.

Some owners open without affiliating, under another name, with the same style of training. Functional fitness, cross training, strength and conditioning. That is a branding and cost decision. What you cannot do is use the name without the affiliation.

4. The space

The space decides how many people fit in a class, and the class decides the revenue. So measure it the other way round. First draw the largest class you want to run, with each person's equipment. Then find a room where it fits, plus a warm-up area, toilets and changing rooms.

Before signing, ask the local authority whether that unit can be used as a gym. A cheap warehouse that cannot get the permit is the most expensive mistake on this list.

What to measure on a viewing, from ceiling height to noise, is in a separate guide. So are the lease clauses to negotiate. Choosing a space for your gym or studio

5. Permits and paperwork

The rules depend on your country, region and city, so confirm them locally before you commit to a date. The list usually covers the right to use the building as a gym, business registration and insurance. Then member contracts and waivers, data protection, and fire safety.

Some countries add rules specific to fitness. Portugal, for example, requires every fitness facility to have a technical lead with a professional licence. It also requires insurance for the people who train there. Ask a local accountant or lawyer which rules apply to you.

A country-agnostic checklist, with the questions to ask locally, is here.

6. Who coaches

Your coaches are the product. Members choose a gym for the people who run the classes far more than for the logo on the wall. Hire for the ability to run a class of twelve safely. That means seeing who is moving badly, scaling the workout and keeping the clock.

Check what your country requires on top of that. The affiliation's Level 1 certificate is a brand requirement. Some countries also require a national licence to coach or to direct a fitness facility. That one is the law.

7. The equipment for the first class

Buy for the biggest class on your timetable, not for the catalogue. If the 19:00 class has twelve spots, you need twelve barbells and twelve pairs of everyday plates. Add the rest of what that week's training uses. Anything only one person uses at a time can wait.

The list by modality, with what to buy first and what can wait, is in its own guide.

8. The timetable and the plans

Open with fewer classes than you think you need. A class of three costs the same coach as a class of twelve. It also drains the energy from the room. Start with the hours your audience can actually make: early morning, lunchtime and early evening. Add classes when the ones you have fill up.

The same goes for plans: few, and easy to explain. Four plans are enough to open. An unlimited plan, a two or three times a week plan, a class pack and a drop-in. Every extra plan is one more question at the front desk.

How many spots each class should have, and why one more costs you later, is covered here. How many spots should a class have

9. Sell before you open

A gym that opens with no members pays rent for months while it fills up. A presale flips that. You start collecting contacts the day you sign the lease, and run a launch event. The first memberships sell at a founding price before the doors open.

How to run the presale, from the interest list to the first payment, is the next guide.

10. The first week

In the first week everyone is seeing the gym for the first time, and that impression sticks. Three things make the difference:

  • Every member has an account and a signed waiver before they arrive. No paperwork at the desk while class is starting.
  • First-week classes have fewer spots than usual, so coaches learn names and correct the people who need it.
  • There is a separate introduction class for people who have never done CrossFit.

A twelve-week calendar

This calendar is a starting point, counted back from opening day. Building work and permits vary from one unit to the next, and they decide whether you need longer.

Weeks before openingWhat is done
12Audience, numbers and break-even. Affiliation application, if you want one.
11 to 10Viewings, with the local authority consulted before signing.
9Lease signed. Permit application and fit-out plans, if needed.
8 to 6Coaches hired. Insurance, house rules and safety procedures.
6Interest list open, with a page for the gym and social accounts.
5 to 4Equipment ordered. Timetable and plans decided.
4Launch event. Presale open at the founding price.
2Equipment installed. Member accounts created and waivers signed.
1Test classes with friends and family. Tune the warm-up and station changes.
0Opening, with smaller classes and an introduction class.
If the fit-out needs a building permit, that permit becomes the critical path and everything else moves around it.

The mistakes that cost the most

  • Signing the lease before knowing whether the unit can be used as a gym.
  • Buying all the equipment before the timetable exists. The timetable decides what you need.
  • Opening with a full timetable and empty classes. A few full classes sell better than many empty ones.
  • Leaving qualified staff out of the numbers. If your country requires a licensed technical lead, that is a wage.
  • Launching a founding price with no end date. A discount without a deadline becomes the price.
  • Leaving waivers, payments and bookings until opening week.

Numbers and permits first, equipment after. That order protects the money that is hardest to win back.

How Rummo helps at opening

Rummo gives your gym a public page at its own address. It shows the live timetable with spots per class, prices, location and a trial class request. Your launch event gets its own sign-up page with a capacity, and paid tickets on paid plans.

Members book from their phone and sign the digital waiver before their first class. On paid plans they pay by card or SEPA Direct Debit, into your own payout account.

The box page shows class capacity, the waitlist, attendance and memberships. CrossFit box software

Frequently asked

Do I need to affiliate to open a CrossFit-style gym?
Only if you want to use the CrossFit name. Affiliation gives you the brand, for an annual fee and a one-time application fee. Without it, you can open a gym with the same style of training under another name.
How long does it take to open a CrossFit gym?
Counting back from opening day, twelve weeks is a workable calendar when the space needs no permitted building work. If it does, the building permit sets the pace.
Is the Level 1 certificate enough to coach?
It is what the brand requires for affiliation. Some countries also require a national licence to coach or to run a fitness facility. Check yours before you hire.
How many members do I need to open?
Enough to cover your fixed monthly cost. Divide that cost by your average revenue per member, after sales tax and payment fees. That is the break-even point, and the presale exists to reach it as early as possible.
Can I open with group classes only?
Yes, and it is the simplest model to run. Open gym and personal training add revenue, and they also add hours and rules. Many gyms add them once group classes are stable.
What should I buy first?
Whatever the biggest class on your timetable uses at the same time. Barbells, plates, rowers or bikes, boxes and kettlebells for every spot. Specialist kit that one person uses at a time can wait.
